This is designed to fruit trees, houses, and then install the pipe rail, power transfer along the pipe rail Automatically relates to a rail bogie to allow for automatic control spraying pesticides, especially the earlier application by the present inventor Patent Application No. 2011 to 0,078,849 from the balance rail mounting of pipes to improve rail (hereinafter referred to as conventional referred to as) while and as well as the ease of dissolution, a shaking or an object of the present invention to provide a curve does not pass though the true deviation bend for long-distance running is easy to automatically control the balance rail. is designed to achieve the above object, configuration instead of the base, locking ring at the top of the lower tension rollers of the rail chukbong of a conventional automatic balance control and, as a link one end hinged to the lower end chukbong one end and the guide plate is hinged to the other end of the link bar, the the hinged bracket and the bottom of the fixed plate to the other end of the guide plate, and a fixed lever to one side of the guide plate, the front end of the fixing plate is configured such that shaft hayeoseo rod through the lower connection of the tension roller, the link shown by the vertical rotation of the lever guide plate of the fixed plate by a hinge bracket by lowering the chukbong center and a lever device that lowers the tension roller But that the conventional division of the power rollers for automatic control on both sides of the rail bogie coupling, hayeoseo consists of fitting inserted by dividing the combined electric roller magnet ring in the middle, to prevent derailment was able to transfer along the pipe rails with magnetic devices including characterized in that configuration.본 고안은 과수, 하우스, 등에 파이프레일을 설치한 다음, 이 파이프레일을 따라 전동이송하면서 자동으로 농약을 살포할 수 있도록 하는 자동방제용 레일대차에 관한 것으로, 특히 본원 고안자가 선출원한 특허출원 제2011-0078849호(이하 종래로 함)를 개량하여 파이프레일로부터 레일대차의 장착 및 해체가 용이함은 물론, 흔들림 또는 커브진 굴곡부를 지나더라도 탈선되지 않아 장거리 주행
